title: Solo ultrasonography-guided percutanous nephrolithotomy for single stone pelvis.
abstract: OBJECTIVE
  To evaluate the success and outcomes of solo ultrasonography (US)-guided percutaneous nephrolithotomy (PCNL) for management of a single stone pelvis.
  
  
  METHODS
  From April 2008 to April 2010, the procedure was applied to 34 patients (22 men and 12 women) whose ages ranged from 25 to 55 years (mean 29.5 y) with unilateral single stone pelvis in a moderately to markedly dilated pelvicaliceal system (PCS). The stone size ranged from 20 to 30 mm (mean 24 mm). Middle caliceal puncture and dilation were performed in all cases by an experienced urologist under US guidance with a needle-guided system attached to the side wall of the US probe. The evaluation of the procedure included the success of accessing the stones, the occurrence of intraoperative or postoperative complications, the stone-free rate, and the need for auxiliary maneuver.
  
  
  RESULTS
  The access was successful in all cases. Minor intraoperative complications occurred in two cases where PCS perforation was detected and was managed conservatively by Double-J stent insertion for 4 weeks. The only reported postoperative complication was fever in five cases that responded to antibiotic treatment. Thirty-two (94%) patients were stone free on postoperative day 2; significant residual stones (8 and 10 mm) were detected in two patients who underwent shockwave lithotripsy, and they became stone free within 10 days.
  
  
  CONCLUSIONS
  Solo US-guided PCNL can be performed safely as an alternative to the fluoroscopy-guided PCNL for single stone pelvis in a moderately to markedly dilated PCS by an experienced urologist.
